PORTABLE RIG FOR PULLING OIL-WELLS.

SPECIFICATION forming part of Letters Patent N 0. 738,353, datedSeptember 8, 1903.

Application filed June 15, 1903- Serial No. 161,463. (No model.)

To all whom it may concern.-

Be it known that I, FRANK W. PENNELL, of Ann Arbor, county of Washtenaw,and State of Michigan, have invented certain new and useful Improvementsin Portable Rigs for Pulling Oil-Wells; and I do hereby declare that thefollowing is a full, clear, and exact description of the invention,which will enable others skilled in the art to which it appertains tomake and use the same, reference being had to the accompanying drawings,and to the figures of reference marked thereon, which form part of thisspecification.

My invention has reference to a portable rig for pulling oil-wells; andit has for its object to provide a rig of simple and inexpensiveconstruction which shall be conveniently portable, being easily set upand taken down and transported from one well to another when it becomesnecessary to pull the same.

To this end my invention comprises the novel arrangement of the partshereinafter shown, described, and claimed.

In the drawings, Figure 1 is a perspective view showing the rigsupported by guy-wires in position for pulling the well. Fig. 2 is aside elevation of the rig lowered for transportation. Fig. 3 is a bottomplan view of the rig, the forward truck being detached.

The rig proper comprises tapering side sections 1 and 2, respectively,spread apart at their lower ends and connected by transverse pieces 3,adapted to provide a broad support for the rig when elevated. At the topof the rig between the upper ends of the sections 1 and 2 is mounted apulley 4, over which the lifting-cable of the rig is operated, anordinary windlass 5 being arranged at the lower ends of the sections 1and 2 to wind and unwind the cable. Near the lower portions of thesections 1 and 2 are permanently attached rollers, or wheels 6, adaptedwhen the rig is lowered to support the weight of the same equallydistributed on opposite sides thereof. These wheels are mounted so as totake a position considerably removed from the side sections 1 and 2, sothat when the rig is lowered from the raised position (shown in Fig. 1)the wheels 6 will be in contact with the ground (indicated by the line aa, Fig. 2) and support the weight of the rig while the latter is stillelevated at an angle of approximately thirty degrees. The weight of therig being now counterbalanced and supported upon the wheels 6, theforward end of the rig may be readily lowered. When lowered for thepurpose of transportation, a detachable truck arranged with suitablewheels 7is provided for the forward end of the rig to rest upon. Thistruck is secured to the rig proper by suitable means, chains beingpreferably employed for this purpose. A tongue or reach attachedto theforward truck permits a team of horses to be hitched thereto to draw therig to the well to be pulled.

'9 represents suitable brace-rods directed over the supports carryingthe wheels 6, the same being secured at the ends 10 to the sections 1and 2, by which means the sections are materially supported, since therig when in useleans forward at an angle to the ground.

From the foregoin git is apparent that I provide a simple, inexpensive,and easily-operated rig for pulling oil-wells, which may be readilytransport-ed from place to place, thereby overcoming. the usualnecessity of maintaining a pullingrig over each well being pumped andresulting in greatly red ueing the expense of pumping a plurality ofwells.

The novelty, utility, and advantages of my invention will be apparent.

Having described my invention, what I claim, and desire to secure byLetters Patent, 1s-

In a portable pulling-rig for oil-wells, the tapering side sectionsprovided with a pulley at their upper ends and joined together at theirlower ends to form a broad support for the rig, wheels mounted upon theside sections near the lower ends, adapted to support the side sectionswhen lowered and to be raised from the ground when the sections areelevated, and the brace-rods carried over the supports for the wheelsand secured at the ends to the side sections, substantially asdescribed.

In testimony that I claim the foregoing as my own I affiX my signaturein presence of two witnesses.

FRANK W. PENNELL.
